Please help me solve this using the distance formula!!

Answer:
51.5 m
Step-by-step explanation:
Plot the points B and C. Then substitute the points in the distance formula.
B(-35,-20)
[tex]\sf x_1= -35 \ ; \ y_1=-20[/tex]
C(-10,25)
[tex]\sf x_2=-10 \ ; \ y_2 = 25[/tex]
[tex]\sf \boxed{\bf Distance = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}[/tex]
[tex]\sf = \sqrt{(-10-[-35])^2+(25-[-20])^2}\\\\=\sqrt{(-10+35)^2+(25+20)^2}\\\\=\sqrt{(25)^2+(45)^2}\\\\=\sqrt{625+2025}\\\\=\sqrt{2650}\\=51.5 \ m[/tex]
